To all whom it may concern:

Be it known that I, FRANK R. Pnnmn-a citizen of the United States, residin at Dearborn, in the county of Wayne and tdte of Michigan, have invented-certain new and useful improvements in Fuel Vaporizers, of which the following is-a description.

My invention belongs to that general class of devices known as fuel Vaporizers, and relates particularly to a device to be used in connection with internal combustion engines, or the like, for assisting in vaporizing thecharge of fuel'or hydrocarbon. 'Ihe invention relates particularly to a device peculiarly adapted to be used in connection with hydrocarbon engines when the heavierhydrocarbons, such as kerosene, for example, or distillates, are used, but is no wise limited to such use. It has for its object the pro.- duction of a device for the purpose stated adapted to be placed between the carburetor and the intake and exhaust ports-of the engine, and that will more perfectly vaporize the passing charge on its pamage from the carburetor to said ports. It also has for its object the roduction of such a device in a simple, e cient, durable and economical.

manner, and which may be available wherever such devices are applicable. To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts,

Fig. 1 is a longitudinal vertical section through a manifold illustrating my invention" i 2 is a section of the same taken substantlally on line 2-2 of Fi 1 Fig. 3 is a partial longitu inal hor1zont.al

,section'taken substantially on the line 3-,-3 ofFig.l;and

Fig. 4 is a section somewhat simllar to the section shown in Fig. 1, illustrating a modification. I

In the drawings,- 1 designates the exhaust manifold which connects with the several exhaust ports 7, 8, 9 and 10, and 5, 6 are intake ports, my improvement bein shown with one of the well known types 0 four-cylinder engines. Leading from the carbureter 2' 1s a fuel passage or a pipe 3, which at its upper end communicates with a chamber or passage runr. varonrznn.

with the intake ports, 5,

4, this latter chamber or passage connecting the exhaust manifold 1 is an auxiliary passage s1de of the intake pipe 3 and heated thereby 11 extending each with which it connects, and at its ends communicating with the intake ports, 5, '6.

In the preferred construction illustrated, the auxiliary passage 11 is provided at its open ng into theintake pipe 3 with deendlng diverting extensio 1S or plates 12.

hese extend inward from the wall of the in-- take pipe 3 above the auxiliary passage, a suitable distance andpreferably de end downward therefrom to a point substantially in line with the lower edge or wall of the said passage. Their action is to direct into the auxiliary passage that portion of the charge extending from the wall of the intake pipe-inward to substantially the vertical plane of the inner ends of said extensions. In the preferred construction, I provide an opening at the top of the chamber or passage 4 and provide the same with. a screw plug 13 provided with a depending stem 14, upon which is loosely maintained a vertically movable valve 15. The exhaust manifold 1 at the point where the intake pipe-3 passes therethrough iswidened as at 16 so as to permit a free passage by the said pipe.

The operation as thus described is as follows: When the engine is idlin or at the time of starting the same, the va ve 15 is on its seat, and an incoming charge sufficient for the operation of the engine is diverted into the auxiliary passage 11, thence to the intake ports 5 and 6, and thence to the valve 15 being sufliciently lifted from its seat by the suction to ermit a portion of the charge to pass there the charge pass- 6. Arranged within ing by said valve and through the chamber or passage 4 being also conducted to the" inlet ports 5 and 6, and there brought in contact with the heated incomin charge through the auxiliary passage 11. %he temperature of the latter part of the charge is greatly increased by reason of the fact that the auxiliar passage is located in the exhaust mani old 1 and heated thereby. As theengine continues to operate, the lighter portions of the incoming hydrocarbon seek the unrestricted passage upward between the plates 12 and thence by the valve 15 and the chamber 4. The heavier liquid, 7 which to an extent depending on the character of the hydrocarbon used tends to contact with and creep up the wall of the pipe 3, is diverted by the depending plates 12 into the auxiliary eliminated. Such a construction is shown in Fig. 4. In this form the construction and operation is substantially the same, except as effected by the removal of the valve shown I in the previous construction. As here shown, the operat1on,1s as follows: As the engine idles or starts the char e is drawn in. through the intake pipe 3 and t ence a portion passes throu h the passage or chamber 4 and a portion. t rough the auxiliary passage 11. The proportions will be modified somewhat by the dimensions of the various cooperating parts. As the engine speeds up to normal operation, the suction increases and the action is then substantially the same as in the form shown in Fig. 1 when the valve is wide open. For accurate operation the form shown in Fig. 1 is preferred, although for some forms of devices the form shown in Fi 4: may be effectively used.

I -Iaving thus described my invention, it is obvious that various immaterial modifications may be made in the same without departin from the spirit of my invention; hence do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned. What I claim as new and desire to secure by Letters Patent is:

1. In a device of the kind described, and in combination, an exhaust manifold, intake ports, -carbureting means, a passage com- Inunicating with the intake ports, an intake pipe communicating with said passage and the carbureting means, an auxiliary passage arranged to be heated by the exhaust manifold, and also communicating with said intake pipe and the intake ports, and means melee?" arranged within the intake pipe for directing a part of the charge passing therethrough into the auxiliary passage, said means comprising diverting plates arranged within the intake pipe above the auxiliary passage and extending downwardly therefrom within the intake pipe.

2. In a device of the kind described and in combination, an exhaust manifold, intake ports, a carbureter, a passage communicating with the intake ports, an intake pipe communicating with the passage and the carbureter, .an auxiliary passage arranged within and heated by the exhaust manifold and also communicating with the intake pipe and the intake ports, said auxiliary passage extending laterally from the intake pipe intermediate the ends of the intake pipe, and means for directing a part of the charge passing through the intake pipe into the auxiliary passage, said means comprising deflecting plates extending inwardly from the walls of the intake pipe and downwardly in front of the inlet of said auxiliary passage.

In a device of the kind described and in combination, an exhaust manifold, intake ports, a carbureter, a passage arranged above theexhaust manifold communicating with the intake ports, an intake pipecommunicatin with the said passage and the carbureter, va ve mechanism arranged at the connection of the intake pipe with the passage, an auxiliary passage arranged within the exhaust manifold, and also communicating with said pipe and said intake ports, and diverting p ates arranged within the intake pipe above the auxiliary passage and extending downwardly therefrom within the intakepipe, whereby in starting the engine or at low speed a suflicient char e is delivered through and heated by the auxiliary passage, but upon speeding the engine up the valve will be automaticall lifted from its seat, and the charge divi ed into two parts, one of which will pass through the first mentioned passage to the intake ports and the other of which will passthrough the auxiliary passage and become heated thereby, the two parts being brought together again before the charge is delivered to the cylinders.

In testimony whereof, I have hereunto signed my name in the presence of two sub= scribing witneses.
